Sleep varies from individual to individual and is essential for maintaining good health, making it important for the health of individuals and societies. Sleep duration is influenced by both genetic and environmental factors, and sleep duration has been reported to be associated with obesity, metabolic syndrome, diabetes, and cardiovascular disease. In this study, we identified SNPs associated with sleep duration from the genome-wide association study (GWAS) catalog and compared them with the Korean Association Resource (KARE) cohort to find SNPs associated with sleep duration in Koreans and to identify the genes involved. The results showed that rs1553132, a SNP in the GRM5 gene, was identified as an SNP associated with sleep duration in both the GWAS catalog and the KARE cohort, and rs1504096 was the first SNP found to be associated with sleep duration in Koreans. It was found that having a minor allele tended to increase sleep duration. These results confirm the reproducibility of the association between sleep duration and the GRM5 gene in Koreans and provide a basis for using the associated SNPs as genetic determinants of sleep duration.

Background: Early detection of neuropathy may prevent further progression of this complication in the diabetic patients. The purpose of this study was to evaluate the prevalence of early neuropathic complication in patients with newly diagnosed type 1 and type 2 diabetes. Methods: Nerve conduction studies (median, ulnar, posterior tibial, peroneal, and sural nerves) were performed for 49 type 1 (27 males, mean $14.1{\pm}7.5$ years) and 40 type 2 (27 males, $42.0{\pm}14.1$ years) diabetic patients at onset of diabetes. Children with age at onset under 4 years and adults over 55 years were excluded to eliminate the aging effect and the influence of obstructive arteriosclerosis. Neuropathy was defined as abnormal nerve conduction findings in two or more nerves including the sural nerve. Results: Mean HbA1c level was $12.6{\pm}3.3%$ for type 1 and $10.5{\pm}2.9%$ for type 2 diabetes. The prevalence of neuropathy was 12.2% for type 1, and 35.0% for type 2 diabetes, respectively. There were significant trends in the prevalence of neuropathy with increasing age (p<0.05). The effect of the mean level of glycosylated hemoglobin on the prevalence of polyneuropathy at onset of diabetes was borderline (p=0.0532). Neither sex of the patients nor the type of diabetes affected the neurophysiologic abnormalities at the diagnosis. Conclusions: Even in a population with diabetes at the diagnosis, the prevalence of subclinical neuropathy was not low. Neuropathy has been significantly associated with increasing age indicating the possibility of longer duration of undetected diabetes among them, especially in type 2 diabetes.

Objectives : The objective of this study is to examine the findings of a survey assessing the treatment and management status of individuals with diabetes and pre-diabetes, along with their inclination to participate in the Korean Medicine Chronic Disease Management Program. Methods : The survey focused on individuals with diabetes and pre-diabetes, gathering information on respondents' demographic details, diabetes diagnosis, duration of diabetes, attitudes and experiences regarding Korean medicine diabetes treatment, and their willingness to participate in the 'Korean Medicine Chronic Disease Management Program'. Results : 33.1% of participants reported prior experience with Korean medicine treatment for diabetes. The intention to actively utilize Korean medicine treatment was positively observed, with a response rate of 61.1% expressing a favorable inclination and 8.9% indicating a negative stance. Furthermore, 75.3% of patients expressed their intention to participate in the 'Korean Medicine Chronic Disease Management Program' in the future. Among those expressing this intention, 81.4% stated a preference for the 'Korean-Western medicine combined management' in the chronic disease management Program. Conclusions : Patients' willingness to participate in 'Korean Medicine Diabetes Management Program' is high, but lack of information about Korean medicine is a factor that deprives people of the opportunity to experience Korean medicine treatment, and non-medical factors such as difficulty in visiting and administrative complexity are factors that impede participation in the 'Korean Medicine Chronic Disease Management Program'. It should be considered for improvement when formulating policies.

A Spitz (5-years old, castrated male) and a Maltese (9-years old, castrated male) were presented with weight loss, polyuria/polydipsia (PU/PD) and depression. Diabetic ketosis was diagnosed based on clinical signs, physical examinations and screening tests (CBC, serum chemistry and urinalysis). The dogs were treated with NPH initially. However, NPH was inadequate to control blood glucose level due to the short duration of the action (< 5 hours). Because of the poor glycemic control with NPH, the dogs showed diabetic complications including weight loss and cataract. After change to glargine, the duration of insulin action was extended up to 11 hours. As a result, there was significant improvement in clinical signs and serum fructosamine concentrations. This study suggests that glargine is useful as a long-acting insulin in dogs which have poor glycemic control due to the short duration of NPH.

Purpose: The purpose of this study was to examine the cognitive function in NIDDM patients. Method: The data were collected at MI OPD in C University hospital. with Digit Span Forward & Backward, Trail Making Test-A, Trail Making Test-B, and MMSE. Result: There were significant differences in DF, DB, TMT-A, and TMT-B according to gender, and in TMT-A according to living with spouse and comorbidity. There were significant differences in DF, DB, TMT-A, TMT-B, and MMSE according to monthly income, and in DF, TMT-A, and TMT-B according to hypertensive state. But, there was no difference in cognitive function score according to diabetes-related complication and diabetes treatment modality. There was a significant positive correlation between duration of NIDDM and TMT-A(r=.215, p=.025). The global cognition score was explained 42.1% of varient by age, duration of education, monthly income, and hypertensive state. Conclusion: As above results showed, among age, duration of education, monthly income, and hypertensive state, prevented and managed hypertensive state which is modifiable factor may reduce or delay cognitive function impairment in NIDDM patients. And DF & DB, TMT-A & B could be more utilized as useful cognitive function measurements because those tests reflected cognitive function in NIDDM patients better than MMSE.

Background: This study aimed to investigate the association between the presence and severity of cardiovascular autonomic neuropathy (CAN) and development of long-term glucose fluctuation in subjects with type 2 diabetes mellitus. Methods: In this retrospective cohort study, subjects with type 2 diabetes mellitus who received cardiovascular autonomic reflex tests (CARTs) at baseline and at least 4-year of follow-up with ${\geq}6$ measures of glycosylated hemoglobin (HbA1c) were included. The severity of CAN was categorized as normal, early, or severe CAN according to the CARTs score. HbA1c variability was measured as the standard deviation (SD), coefficient of variation, and adjusted SD of serial HbA1c measurements. Results: A total of 681 subjects were analyzed (294 normal, 318 early, and 69 severe CAN). The HbA1c variability index values showed a positive relationship with the severity of CAN. Multivariable logistic regression analysis showed that CAN was significantly associated with the risk of developing higher HbA1c variability (SD) after adjusting for age, sex, body mass index, diabetes duration, mean HbA1c, heart rate, glomerular filtration rate, diabetic retinopathy, coronary artery disease, insulin use, and anti-hypertensive medication (early CAN: odds ratio [OR], 1.65; 95% confidence interval [CI], 1.12 to 2.43) (severe CAN: OR, 2.86; 95% CI, 1.47 to 5.56). This association was more prominent in subjects who had a longer duration of diabetes (>10 years) and lower mean HbA1c (<7%). Conclusion: CAN is an independent risk factor for future higher HbA1c variability in subjects with type 2 diabetes mellitus. Tailored therapy for stabilizing glucose fluctuation should be emphasized in subjects with CAN.

BACKGROUND/OBJECTIVES: The prevalence of diabetes has continued to increase globally. Changes in eating habits, lack of exercise, increased stress, and aging are major contributors. Glycemic control is the key strategy of diabetes management. The purpose of this study was to analyze the utilization of nutrition labels and related factors among patients with diabetes. MATERIALS/METHODS: Data from the 7th Korea National Health and Nutrition Examination Survey were used. General, health-related, diabetes-related characteristics from 1,587 adults with diabetes history were included. Nutrition label utilization was assessed with awareness and use of nutrition labels and effects on food choice. For statistical analyses, chi-square test and multiple logistic regression analysis were performed. RESULTS: The prevalence of awareness, use, and effects of nutrition labels on food choice among diabetic patients were 48.8%, 11.4%, and 9.6%, respectively. High monthly income, walking frequency, family history of diabetes, younger age at diagnosis, and shorter duration of diabetes were associated with higher nutrition label awareness. Nutrition label use and effect on food choice were higher in women, those with high monthly income, those diagnosed at younger than 45 yrs, those with diabetes for less than 10 yrs, those with meal therapy, or patients who had undergone a fundus examination. CONCLUSIONS: Nutrition label utilization status was low in Korean patients with diabetes. Strategies are needed to promote nutrition label use as a diet management tool for patients with diabetes.

Background: Prior studies examining the relation between diabetes mellitus (DM) and prostate cancer risk have reported controversial findings. We examined this association by conducting a detailed meta-analysis of the peer-reviewed literature. Methods: A comprehensive search for articles of MEDLINE and EMBASE databases and bibliographies of retrieved articles published up to November, 2012 was performed. Methodological quality assessment of the trials was based on the Newcastle-Ottawa Scaleq and the meta-analysis was performed using STATA 12.0. Dose-response regression was conducted with SPSS 19.0. Results: We included 29 studies in the meta-analysis (13 case-control studies, 16 cohort studies), and found an inverse association between DM and prostate cancer (relative risk (RR) 0.84, 95% confidence interval (CI), 0.78-0.91). An inverse association was also observed in non-Asian populations (RR 0.81, 95% CI 0.76-0.87) and population-based studies (RR 0.80, 95% CI 0.77-0.91). No statistical significance was found of the association between prostate cancer risk and the duration of DM (p=0.338), and risk seemed not related with the age of DM diagnosis. Conclusions: This study suggested an inverse relationship between DM and prostate cancer, but without links to duration of disease or age of diagnosis.

당뇨병은 인슐린 분비 또는 인슐린 작용의 장애로 발생하는 대사질환이다. 그 중 제1형 당뇨병은 흔히 혈당 조절이 어려우며 눈과 신장을 침범하는 미세혈관합병증이 발생할 수 있다. 당뇨병성 신병증은 소아에서 흔하지 않지만 신부전까지 일으킬 수 있는 심각한 질환이다. 그런데, 많은 연구들에서 당뇨병이 사춘기 전에 발생하는 경우보다 사춘기나 그 이후에 발생하는 경우에 미세혈관 합병증의 발생이 증가한다는 사실이 알려졌다. 사춘기 전에 발생한 소아 당뇨병성 신병증은 국내에서 보고된 예가 거의 없는 상태로, 저자들은 여러 차례의 당뇨병성 케톤산혈증의 과거력이 있으며 혈당 조절이 불량했던 제 1형 당뇨병 소아 환자에서 혈뇨와 단백뇨가 관찰되어 조직 검사를 통해 사춘기 전에 발생한 당뇨병성 신병증을 확진한 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
